FS Series - Plus Audio

The FS Series line array and subwoofers represent Plus Audio’s pinnacle of innovation and acoustic excellence in loudspeaker technology.

Designed for uncompromising performance and rapid deployment, FS Series systems offer scalable, high-output solutions tailored for touring professionals, rental companies, and live event venue integrators.

Built with premium components and engineered for sonic precision, the FS Series delivers consistent coverage, intuitive rigging, and seamless system integration.

Touring Ready

Constructed from premium plywood and coated in weather-resistant polyurethane, the FS series is built for the demands of touring life—indoors or out. Custom built carts and weatherproof bags allow for efficient transport logistics.

Precision Performance

FS line array cabinets all feature advanced DSP filtering, the same 3″ high frequency compression drivers, and are optimized for high SPL, reduced comb filtering, and enhanced clarity across the intended coverage area.

The loudspeakers share complementary acoustic performance, rigging mechanics, and enclosure design, ensuring seamless integration and uniform system voicing.

Presettable Rigging System

The FS series rigging system allows setting of preconfigured splay angles directly on the ground. A dedicated rear rigging strand locks each cabinet into position as the array is lifted, eliminating the need for manual angle adjustment in the air. Splay angles between FS line array cabinets can be set from 0° to 10° in 1° increments.

Extreme Bass Reproduction

The FS subwoofers are designed for high-performance and maximum low-frequency extension and definition. Utilizing long-excursion drivers, the single and dual 19″ FS subwoofers combine the transient speed of 18″ drivers with the depth and extended frequency range of 21″ subs—without compromise.

A cardioid-ready design includes front and rear panel connections for flexible deployment. Up to 16 FS subs can be flown on a single array frame.
The FS subwoofer range delivers exceptional output, low distortion, and a powerful sub-bass experience that remains controlled and musical at extreme SPLs.
